Continental are trumpeting the eco-credentials of the new ContiEcoContact 5 which was developed in co-operation with Europe’s leading car manufacturers.
According to the German tyres manufacturer it sets new standards in terms of the environment and also improves safety.
The challenge facing tyre companies is to design a tyre that reduces rolling resistance and wear whilst also ensuring that it is still good at wet braking.
To achieve this, Conti’s tyre engineers started with a new approach to all four components of the tyre – design, contour, compound and tread pattern.
The result is a tyre that delivers reduced CO2 emissions and lower fuel consumption while still delivering excellent braking performance.
According to Continental: “This means that the ContiEcoContact 5 has 20% better rolling resistance than its predecessor leading to a 3% reduction in fuel consumption. Engineers have also improved wear by 12% and braking on wet roads by 10%.
“A specially developed compound and optimised tread grooves have lead to an improvement in grip in the wet. Continental’s tyre designers have combined this with functionalised polymer chains forming a stronger bond with the silica which gives lower rolling resistance. Extra thin sipes reduce tread deformation minimising energy loss.
“A higher apex and the use of additional bead reinforcements ensure safer and more direct transmission of the lateral forces which occur when steering on wet and dry roads. The lighter sidewall construction is more flexible in its design which also contributes towards improved rolling resistance.
The engineers also found that the tyre’s ground contact patch offered scope for reducing rolling resistance. The tyre developers at Continental managed to lessen movement in the belt structure by using a very flat contour and adapting the distribution of tread depths to suit this.”
The engineers also looked at the sidewall lettering on the tyre. A flatter, more smooth design now reduces the drag on the car helping to improve the aerodynamics of the overall vehicle.
The ContiEcoContact 5 is currently available in size 14-16 rim sizes.
